AUXILIARY WARMTH WITH 
ELECTRIC CONTROL 


Warmth with the same ease as light from an 
electric lamp is the contribution of the Corto 
Electric Steam Radiator to the comfort of the 
home. What a convenience during the frosty 
mornings of late autumn or the cold, damp days of 
early spring, when warmth is usually needed for 
only a few hours a day, to secure just the right 
amount with the turn of a switch. Then, too, there is often a room, 
hall or sun parlor to which the Corto Electric Steam Radiator can 
bring the additional warmth needed for complete comfort during 
especially severe weather. It is also an ideal solution of the heating 
needs of summer homes and homes in the south and on the west 
coast where warmth is not needed regularly. 


cA ‘Radiator of “Distinctive “Beauty 


Designed by a French Engineer imbued with the traditions of 
atartistic race, the @ortovis a radiator of ‘classic beauty... “ltis the 
delight of both interior decorators and discriminating home-owners, 
for its graceful Gothic lines readily harmonize with any interior, 
and it occupies a third less space than the usual radiator of equal 
heating surface. It may be painted or enameled in any color to 
match its surroundings, and may also be obtained in a glistening 
white porcelain enamel to match bathroom fixtures.

Quick Heating 


Because of its slender columns, the Corto Electric Steam Radi- 
ator has a very small water content in proportion to its surface. This 
is a great advantage, for the small volume of water is quickly heated, 
and warmth is given off very shortly after the current is turned on. 


cA (up of ‘Water a Year 
Its Only “Requirement 


A single filling of water is the only attention the Corto Electric 
Steam Radiator needs for an entire year of service, for in this time 
it evaporates less than a cup of water. Operation is simplicity 
itself: the control, an ordinary three- 
heat electric switch, need only be 
turned to “high,” “medium,” or ‘low,’ 
for the amount of warmth desired. 


SIX 


CHealthful, Effective, Clean, and Safe 


Unlike both gas and electric heaters of the radiant type that 
parch the air by intensive heating and heat only the space directly 
in front of them, the Corto Electric Steam Radiator warms the air 
gently and evenly in large volumes and circulates it throughout the 
room. No ashes, soot, noise, odor, or excessive moisture are con- 
nected with its use. No exposed hot parts endanger members of 
the family or surrounding objects; water splashed on it does no harm. 


“Readily eAloved to cAny “Room 


The Corto Electric Steam Radiator is much lighter than the 
usual type of radiator, and as no flue or piping is required, it may 
easily be moved to any room with a proper electrical connection. 
In the summer, when it is not needed, it may 
be removed and stored. This portable feature 
makes it especially suitable for use in buildings 
under construction and on yachts and ships. 


Sever_s 


One Sundred “Per (Cent Efficient 


This unique heating unit operates at the absolute maximum of 
efficiency—100%. Every unit of electricity supplied to it is trans- 
formed into heat. As current is used only when warmth is actually 
needed, and 50% and 75% less is used on medium and low than 
on full current, operating costs are moderate. A few cents a day 
will provide all the warmth necessary to remove the chill from 
bedroom, bathroom, or favorite corner. A table of operating costs 
for different current rates is given on page 12.

cA Mechanically “Perfect “Radiator 
and a Sturdy ‘Heating Unit 


Corto Electric Steam Radiator sections are joined by threaded 
nipples of malleable iron instead of tapered slip nipples and un- 
sightly iron rods. This construction provides two joints instead 
of the usual one, and is the safest and most satisfactory of radiator 
connections. It is an exclusive feature of American Radiators. 


The immersion unit is of especially rugged construction. It is of 
a standard type that has been in use for many years, and will last 
indefinitely. 


Equipmenm~ 


Equipment consists of filler and cap, safety valve, air vent, 
heating element, three-heat electric switch, and five foot cord. The 
switch is regularly clamped to the radiator, but may be fastened to 
a wall, if desired.

SIZE REQUIREMENTS 


The following table gives factors by which to multiply 
wall and glass surface and exposed volume to determine 
watts required for heating to seventy degrees (without 
other source of heat) for any outside condition.

Add watts obtained from the table and exposure allowance and 
select a radiator with input equal to or next above this sum.
